WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 313,093, dated March 3, 1885. Application filed November 29, 1854. (No model.)

To all whom it may concern.-

Be it known that I. ROBERT E. MoOLEL- LAND, a citizen of the United States, residing at Williamsville, in the county of Sangamon and State of Illinois, have invented a new and useful \VagonBrake, of which the following is a specification.

My invention relates to automatic wagonbrakes operated by the team when holding back on the tongue of the wagon.

The object of my invention is, first, to set the brake only when it is needed; second, to provide a leverage in applying the brake after it has come in contact with the wheels; and, third, to remove the brake entirely from the wheels before the forward force of the team is applied to start the wagon. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of the front part of the wagon. Fig. 2 is a top view of the same to show the manner in which the brake is attached to the wagon and operated, as above stated. Fig. 3 is a front view of an iron casting used in the construct-ion of the wagontongue.

The brakeis applied to the front side of the fore wheels only. It consists of a wooden cross-bar, B B, which rests on the tongue and hounds of the wagon; or it may also be hung to the under side of the tongue. The small arms 5 b are of iron, held firmly in place by the pivot-bolts through the inner ends and the iron supports S S, attached to the ends B B. The outer ends of the arms b b carry the brake-blocks. I

The brake is applied by means of the slotted tongue, which slips backward or forward the length of the slot F by the action of the team. The back end of the tongue and tonguehonnds are framed together by means of an iron casting, D. Fig. 3, the ends of the arms A A being bolted to the tongue hounds, and the tongue passes through the opening 0. The large tongue-bolt also passes crosswise through the casting, as shown in Figs. 1 and 2. To the end of the tongue on the under side is bolted a small casting, O, to which the lower end of the lever L is attached. Near the shoulder H of the lever L is attached the brake-rod B. \Vhen the backward force is applied, the tongue slips back and the shoulder H of the lever L bears against the edge E of the casting D, and the whole lever slips back at the same rate as the tongue, carrying the brake with it. As the brake comes against the wheels, the shoulder H passes the edge E and slips up behind it, which then forms a fulcrum for the lever, and the brake is then applied with great force. WVhen the wagon is backed, the friction of the wheels lifts the brake and throws b 1) into the upper and forward shoulder of the supports S S, which lets the brake clear the wheels. B B is held in place by the iron slides G G bolted to the wagon-hounds. On the tongue, back of B B, is bolted an iron shoulder, K, which forces the brake forward with the tongue, so the brake is off the wheels before the wagon is started.

Having thus fully described my invention, what I desire to claim by Letters Patent is 1. The bar B B, the arms b 1 the supports S S, and the slides G G, combined and used on or underneath the wagon tongue and hounds, substantially as set forth.

2. The castings D, O, and K and the lever L, constructed and combined substantially as described, for the purposes specified.
